Snugpak 2nd Skinz Coolmax Long-Sleeve Base Layer — Olive

The Snugpak 2nd Skinz Coolmax long-sleeve is a Coolmax-fibre base layer designed for anyone spending extended hours moving in the field: shooters, hunters and operators who need to stay dry both under protective clothing and when exposed directly to the environment. The 81 cm sleeves give full wrist coverage, closing the gaps that open up when raising your arms with a rifle shouldered.

The thermal behaviour of Coolmax fibre relies on moisture transport: the micro-fine fibres wick sweat produced during intense activity and spread it across a wider surface area, where it evaporates faster. In practical terms, the shirt does not become saturated and does not sit cold against the skin when effort drops off — for example during a long wait in a hide or a slow change of position. It does not replace an insulating layer, but it enables one to work: keeping skin dry is the prerequisite for any subsequent layer to function properly.

As a base layer worn under a softshell, combat shirt or hunting clothing, the close fit prevents fabric bunching that could interfere with harnesses, tactical vests or slings. The trade-off to keep in mind is that a fit this snug — optimal for moisture transport and a low profile — is less comfortable as a standalone layer in static situations at low temperatures: in that scenario heat loss outweighs the benefit of rapid drying, and an insulating mid-layer should be added.

Key points

• Coolmax fibres carry sweat away from the skin, keeping it dry after sustained effort and reducing wet-chill during periods of inactivity.
• The 81 cm long sleeves maintain full wrist coverage in any shooting position or task requiring raised arms.
• The close fit sits cleanly under tactical vests, plate carriers and layered hunting clothing without bunching or restricting movement.
• Works in both thermal directions: it slows overheating during activity and limits heat loss during breaks, provided an appropriate outer layer is added for cold conditions.
